Each and every day your computer creates temporary files, log files, installation files, system files, and many other junk files that are not necessary. Over the course of several days or weeks these junk files accumulate using up hard drive space that could be used for applications. These junk files are usually small and will fragment your hard drive causing it to work harder. This fragmentation will cause your PC to run slowly. With Drive Cleaner there is no need for complicated configuration, just choose the drive to be cleaned and click Start, that's it! Drive Cleaner will quickly and efficiently remove these files from your hard drive freeing up potentially tens of gigabytes of data.
